Tesla Motors’ Devastating Design Problem

Tesla Motors' lineup of all-electric vehicles — its existing Roadster, almost certainly its impending Model S, and possibly its future Model X — apparently suffer from a severe limitation that can largely destroy the value of the vehicle. If the battery is ever totally discharged, the owner is left with what Tesla describes as a "brick": a completely immobile vehicle that cannot be started or even pushed down the street. The only known remedy is for the owner to pay Tesla approximately $40,000 to replace the entire battery. Unlike practically every other modern car problem, neither Tesla's warranty nor typical car insurance policies provide any protection from this major financial loss. Here's how it happens.

Despite this "brick" scenario having occurred several times already, Tesla has publicly downplayed the severity of battery depletion risk to both existing owners and future buyers. Privately though, Tesla has gone to great lengths to prevent this potentially brand-destroying incident from happening more often, including possibly engaging in GPS tracking of a vehicle without the owner's knowledge. UPDATE 2!
NOTE (UPDATED!): The argument outlined in this story by Michael DeGusta that originally appeared on has been confirmed by Tesla with the following statement:
All automobiles require some level of owner care. For example, combustion vehicles require regular oil changes or the engine will be destroyed. Electric vehicles should be plugged in and charging when not in use for maximum performance. All batteries are subject to damage if the charge is kept at zero for long periods of time. However, Tesla avoids this problem in virtually all instances with numerous counter-measures. Tesla batteries can remain unplugged for weeks (even months), without reaching zero state of charge. Owners of Roadster 2.0 and all subsequent Tesla products can request that their vehicle alert Tesla if SOC falls to a low level. All Tesla vehicles emit various visual and audible warnings if the battery pack falls below 5 percent SOC. Tesla provides extensive maintenance recommendations as part of the customer experience.
